Abstract

An exhaust gas purging catalyst (3), includes: an integrated carrier (5); and a catalyst coat layer (4) formed on the integrated carrier (5), the catalyst coat layer (4) including a catalyst component (4A) and meeting a following expression (A): P ≥ 0.17W - 0.04 --- (A). P denotes a summation (ml) of a capacity of a void (7) per mass (g) of the catalyst coat layer (4), the void (7) having a pore diameter of 0.1 µm to 1 µm, and W denotes a volume (ml) of the catalyst coat layer (4) per the mass (g) of the catalyst coat layer (4).
